This paper reports on the NTIRE 2021 challenge on perceptual image quality assessment (IQA), held in conjunction with the New Trends in Image Restoration and Enhancement workshop (NTIRE) workshop at ...CVPR 2021. As a new type of image processing technology, perceptual image processing algorithms based on Generative Adversarial Networks (GAN) have produced images with more realistic textures. These output images have completely different characteristics from traditional distortions, thus pose a new challenge for IQA methods to evaluate their visual quality. In comparison with previous IQA challenges, the training and testing datasets in this challenge include the outputs of perceptual image processing algorithms and the corresponding subjective scores. Thus they can be used to develop and evaluate IQA methods on GAN-based distortions. The challenge has 270 registered participants in total. In the final testing stage, 13 participating teams submitted their models and fact sheets. Almost all of them have achieved much better results than existing IQA methods, while the winning method can demonstrate state-of-the-art performance.
At present, most enterprises have a heterogeneous environment of legacy application, which lead to many “information isolated islands”. Enterprises become more and more eager to share data in ...business processes over different systems. Traditional Enterprise Application Integration (EAI) methods usually integrate applications from peer to peer which has many defects. In This paper, a kind of EAI framework based on Web Services (WSEAI) has been put forward, which has nothing with any platform and programming language, so it can make the enterprise applications integrated together without gap. We have been successfully putting the EAI framework in one logistical company’s WebGPS system and realized the integration based on Web Services.
